Cloth simulation plus attached object

Question

I have 2 objects. Zipper and a case. Both objects have a cloth simulation. I need to connect these objects together to animate together and create something like in the third image.

I tried to merge objects into one, vertex parent zipper and case, pin case to the zipper... But none of that worked. Maybe I tried the wrong way.

Is there a way how to get the two objects into one and achieve they correctly deform together?

Answer 1

Finaly I solved it with MeshDeform Modifier. It is simple and effective.

I made a mesh arround zipper and case and assign Cloth Simulation to it. Then I assigned MeshDeform to the zipper and the case and for Object I used the mesh with Cloth Simulation.

I followed this tutorial: blender Quick Tips - Cloth Simulation for Animations
